You still have ping, so the network stack is still functioning, so it's not completely dead. I would recommend keeping tabs on: top # for memory leaking processes netstat -m # for mbuf usage pstat -T # for file usage If these get out of hand then the system could be spewing error messages but you can't see them. If you want to learn how, the proper solution would be to compile in DDB and drop to DDB when it freezes. At least from DDB you can poke around a bit. But this is a procedure that even I don't know how to use :) Doug White | University of Oregon Internet: dwhite@resnet.uoregon.edu | Residence Networking Assistant http://gladstone.uoregon.edu/~dwhite | Computer Science Major To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
